These are -O vs -O + late-dmd-anal I assume. It'd be worth doing the same with -O2 vis -O2 + late-dmd-anal

nofib runs with -O2 by default. Here's an example command that nofib runs to compile of the benchmarks: {{{ ghc-stage2 -O2 -Rghc-timing -H32m -hisuf hi -rtsopts -c Main.hs -o Main.o }}} with `-flate-dmd-anal`: {{{ ghc-stage2 -O2 -Rghc-timing -H32m -hisuf hi -flate-dmd-anal -rtsopts -c Main.hs -o Main.o }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/6087#comment:21 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
